Figure 1. Inflammatory cell infiltrate in excisional wounds in oral mucosa and skin. (A) Neutrophil content as measured by total wound MPO level. Each bar represents the mean ± SE of 6 independent measurements. (B) The mean macrophage number per high power field (HPF) ± SE in wounds. Macrophage infiltration was analyzed by immunohistochemical staining of wound sections and quantitation of MOMA-2 immunopositive cells (n = 6). **p < 0.01; ***p < 0.001 by Student’s t test.
